Hi to all, I'am new and I have installed b4a in Windows 10 PC.
After Click on Open Sdk Manager button and install all nedeed and checked package I have this messag at end of install :

WARNING: An illegal reflective access operation has occurred

WARNING: Illegal reflective access by com.sun.xml.bind.v2.runtime.reflect.opt.Injector$1 (file:/C:/android/tools/bin/jaxb-impl-2.1.jar) to method java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int)

Can you help me to say what are this problem ?
Last 2 questions is : 1.Can I download openjdk version 12 and use this with b4a?
2.Is the openjdk free of charge(not pay royaltis to oracle) ?

Thanks and sorry for my bad English translated.

1. No. You should use Java 8 or 11 for now. Note that you need to use B4A 9.01+ for java 11.
You can find the instructions here: https://www.b4x.com/b4a.html#installation

2. Yes, it is free.

The last warning you can ignore. For the others you need to wait for another answer.
